This paper deals with the initial-value problem for the linearized equations of coupled sound and heat flow, in a bounded domain Ω in ${\mathbb{R}^N}$, with homogeneous Dirichlet boundary conditions. Existence and uniqueness of solutions to the problem are established by using the Hille-Yosida theorem. This paper gives a simpler proof than one by Carasso (1975). Moreover, regularity of solutions is established.

Abstract
This paper deals with the initial-value problem for the linearized equations of coupled sound and heat flow, in a bounded domain Ω in ${\mathbb{R}^N}$, with homogeneous Dirichlet boundary conditions. Existence and uniqueness of solutions to the problem are established by using the Hille-Yosida theorem. This paper gives a simpler proof than one by Carasso (1975). Moreover, regularity of solutions is established.
